Implementation of the invention

The term "motor skill" is understood as a mental or psychomotor mechanism that ensures the implementation of a motor act. A motor skill is a perfect and usually automated skill. In order to assess how the motor skill is being improved, the present invention proposes to compare the user's current skill with the reference one. To do this, during the training process, the user is shown examples of performing reference movements. Each mentioned example is preferably based on a reference motion model preset in advance for each motion that the user is working on developing. Preset models of sports movements are a set of key points of the human body involved in the execution of the movement.

In accordance with FIG. 1, the control module 101 can be represented by a computer device capable of communicating with a mobile user device 102, sensors 103 capable of recognizing key points of the user's body 104 that are involved when the user performs sports movements, and additionally a video camera 105 oriented per user 104. In the field of view of user 104 is a display device 106. Sensors 103 can be either contact or non-contact. The contact sensors 103 can be installed on the body of the user 104, and the contactless sensors 103 can be installed at a distance from the user 104 that does not exceed their range.

The user 104 can, through the mobile user device 102, enter his anthropometric parameters, for example, weight, height, length of legs and arms, and other parameters. The input of the anthropometric parameters 201 can be carried out under the supervision of a trainer or a trainer of the training program, who remotely accompanies the user 104. Then, the device 102 via a communication channel, for example, the Internet, transmits the anthropometric parameters 201 (FIG. 2) to the control module 101.

After receiving the anthropometric parameters 201, the control module 101 initiates the neural network 301 (FIG. 3), to the input of which the parameters 201 are fed, the hidden layers of the neural network 301 recognize the adaptive coefficients k ₁ ... k _n (n is the number of distances between the key points of the person involved when performing movements), the output of the network 301 returns the values of the coefficients for the specific user 104, whose anthropometric parameters 201 were entered. Then, the control module 101 adapts 302 dynamic reference models 202 taking into account the coefficients calculated by the neural network for the particular user 104. Dynamic reference models 202 are sets of key points of the human body involved in the correct execution of sports movement. 202 models can be created using a variety of human motion controllers such as the Microsoft Kinect. The training of models is carried out with the participation of a person whose sports motor skills are sufficient to obtain reference examples of the execution of movements. Based on the results of the adaptation 302, examples of the correct execution of the movements 303 are generated, adapted for the user.

The user 104 can select a training program that includes practicing certain motor movements on the device 102. The device 102 transmits the user's 104 selection to the module 101, from where the corresponding examples of the execution of movements adapted for the user 104 are downloaded. Examples of the execution of the movements, which are video clips or sets of still images, transmitted to the display device 106. When the user 104 performs movements, the sensors 103 recognize the points of the user's body 104 involved in the execution of the movements. The recognized points 203 are sent to the control unit 101, where 304 are matched with points from the examples of the movements 303, adapted for the user. Discrepancies between the recognized points and points from the examples of movements are recorded on the control module and then the matching results are sent to the user device 102 in the form of personal recommendations 204. The personal recommendations 204 may include instructions for the user on how to correctly position body parts in space when performing a sports movement, how to correct the handling of a sports equipment, as well as theoretical information about the correctness of the movement. Recommendations 204 may also be played back on display 106 while exercising movements by user 104.

Additionally, based on the results of comparison 304, the progress 305 of the user 104 is recorded, taking into account which the training program can be adjusted. Progress 305 may also be transmitted to user device 102. In such a case, user device 102 may be capable of returning motor performance progress data to user 104, testing the user's theoretical skills, and showing the user progress in their chosen exercise program.

The process of training a motor skill can additionally be recorded by a video camera 105 in the form of a video recording, stored on the control unit and then reproduced to the user on the user device 102 or on the display device 106. The video recordings can then be used for a more detailed analysis of the training process with the user 104 and the personal trainer. or a workout mentor.

When conducting trainings related to the development of motor skills and skills for playing tennis, examples of correct execution of movements are used, prepared by the coach, taking into account methodological recommendations, reference books and training programs that are traditional for this sport. For example, the following types of sports movements typical for playing tennis can be prepared in advance: "serving the ball", "receiving the ball", "right hand (forehand)", "left hand (backhand)", "rally", " overhead blow (smash) "," cut blow (slice) "," candle "," shortened blow ". When preparing dynamic reference models for each type of movement, mainly use the points located on the following parts of the human body: heels, knees, legs, neck, shoulders, elbows, hands, eyes, ears. Additionally, points located on parts of a sports equipment can be used: the head, neck and handle of a tennis racket.
